Internet of Things (IoT) presents a scenario in which billions of devices are interconnected and distributed almost anywhere, from the human being bodies to the most remote areas of the planet. In general, computer attacks, can steal or modify important data, bring down critical online services or obtain money illegally. On the other hand, in an IoT context, in addition to all these actions, there are possibilities of doing physical harm to people at a distance or manipulating critical infrastructures. This work proposes a FPGAs (Field Programmable Logic Array), with reconfiguration capabilities and great computational power, as a development alternative to the problems presented by the secure implementation of IoT systems.
